TROLLEY.

Be it known that I, Hanvnr JoLLr, a citil zen of the` United States; anda resident of `the `city ofMichigan City, county of Laporte, and State of Indiana, haveinvented certain new and useful "1 Improvements in Trolleys, of which thefollowing is a speci- My i invention, relates to, improvements `in trolleys and has for its object the production of a trolley adapted to effectually engage the conductor wire so as to secure an. effective electrical connection between the conductor wire and the vehicle andwhich will engage the conductor jwire in such a manner as to minimize the possibility ofjumping off the trolley from the wire.

reference to the accompanying drawing A further object is the production of a i trolley which will be of durable and economical construction and eflicient in use.

` Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of parts hereinafter described and claimed. I

Theinvention will be best; understood by forming a part of this specification, and in which-` 5 p Figure l is a side elevation of atrolley embodying my invention,"` the saine` being shown arranged in contact with a conductor wire, Fig.` 2 is a centralfvertical section of the trolley, Fig. 3 is a topiplaln view thereof, and Fig. `4 is a vertical transverse section `taken on line m-m of Fig.

The preferred `form of construction as illustrated in` the drawing comprises the p conventional. trolley pole lfat the upper end y `of whicliis rigidly secured a `housing 2, a bracemember 3 cooperating with saidhousing to effect a more rigid connection` thereof with the trolley pole. The housing is provided at its upper side with a longitudinally i extending channel or recesslt the bottom of which is of curved formation as clearly shown in Fig. 2. `Mounted in the channel "1l-.is a harp 5 of substantially rectangular form, the under side ofsaid harp being curved to correspond with the curvature of the bottom of said channel so as to permit of rocking movement of said hai-p relative to said housing in the operation of the trolley.`

Said harp is secured in position inthe chan-` nele by means of a transverselyextending` pin 6 which engages a transversely extend- Specicatioxi of Letters Patent.

`for the accommodation or reception `of thereof in the lower portion of harp 5.

ing `arcuate slot 7 formed for the reception l .The i upper side of `harp `5 is provided t with .a longitudinally` extending` f recess 8 ,y

the conductor Wire 9. `The bottom of the recess 8 is provided .with a` 4pluralityyof transversely extending recesses 10 inwhich are rotatablymounted contact `rollers 1 l1 secured in position by `transversely eX- tending` pins or bolts l2. The side walls i 13 of the harp 5 are provided with trans-` versely extending substantially rectangular slots 14 in which are arranged contactmrollers 15` mounted for rotary move` ment uponvertically extending pins or bolts 'lG threaded into the harp 5 as clearly shown in F ig. 4. With this arrangement` it will r be `seen that the bottom `and y sides of the `recess 8 will be lined with contactrollers for engagement with the conductor wire 9', i

the result being alleviation of friction with the advantage of the incidental benefits which arise by reason of such alleviation., j

The slots 14 for the reception of the` contact rollers 15 open laterally in the side walls 13` of the harp which permits of the admission `of `,cool air to said rollers preventing ,over-` heatingthereof during the use of the trolley.` Also by `formingsaid slots directly in the flanges 13 so thatthe Iuppersides of said slots are closed by a Strap or wall formed integral with said flanges, a strong and dur- `1: M

able as well as an economical construction is effected.

Provided at thefrontand `rear ends of harp `5 j at the respective extremities of the recess S are blades-l7 the lower ends of` `which are rigidly secured to said harp, the

upper end portions of said plates being bent outwardly at an angle for projection into close proximity with the under side of the; l'

conductor wire when the device is in Zuse.` The blades 17 during the use of the device` constitute scraping means serving to, re-

`move any sleet, ice,\or other foreign matter which may gatherat the under sideof the conductor wire, thereby obviating tlieldiii` culties in electrical conduction which otherwise arise by reason of presence `of sleet,` ice` or otherforeign matter at the under side,

of the conductor wire as is generally known. 1 The angular disposition of theupper `orice y y and sleet` contacting edge i portions of 'the bladeslf? lends resiliency to said portions of said blades which assists in the wire cleaning Operation of said blades.

While I have illustrated and described the i preferred form of construction for carrying my invention into effect, this is capable of variation and modification without departing from the spirit of the invention. I, therefore, do not wish to be limited to thev precise details of Construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claim.-

Having described my invention what I claim as new and desire to secure by Letters Patent is:

The combination with a trolley pole and a Conductor, of a harp adjustably mounted on yice* scraper secured to said harp andV inclined upwardly and forwardly from said harp with itsupper end vspaced slightly from said conductor and adapted to remove ice and sleet from the latter, substantially as described. y

In testimony whereof I lhavel signed my name to this specification in thel presence of ,v

two subscribing witnesses.
